question about eggs on day 50

my eggs are on day 50 but they have not started to dimple or anything. should I be worried or is this normal? the humidity is about 100 percent in there egg tub. is there anything I should do to help them dimple or should they stay plump?

Totally normal, they will do this as they get closer to hatching, the albumen starts to disappear to allow the snake room to cut out, also in the wild it would cut down on the amount of smell the hatching babies would produce to attract predators.

i have my clutch stay like that until the babies hatch..no dimple,dented etc..its normal..

That's actually a great sign that you're doing it right. It's when the eggs start to dimple too soon that you may have a problem. Mine never start to dimple until a week to just days prior to hatching.

Agree with everyone, it's normal. Just let them be and they will emerge when they are ready.
